How to solve indices with different bases
WebWhen multiplying numbers in exponent notation with the same base, we can add the exponents. Consider: a 2 × a 3 = (a × a) × (a × a × a) = a 2 + 3 = a 5 This is the first law of exponents: a m × a n = a m + n Example: Simplify the following; give your answers in exponent form a) 3 3 × 3 2 b) x 5 × x 3 Solution: a) 3 3 × 3 2 = 3 3 + 2 = 3 5 WebFor examples and practice questions on each of the rules of indices, as well as how to evaluate calculations with indices with different bases, follow the links below.

To multiply together two identical values... WebMay 29, 2024 · It is possible to multiply exponents with different bases, but there’s one important catch: the exponents have to be the same. Here’s how you do it: 5^4 × 2^4 = ? First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same. 5^4 × 2^4 = 10^4 This is why it works:
Web7 of 9. The base values are the same (x). Subtracting the two indices must make 2. Starting at 5, work out what needs to be added/subtracted in order to get to 2 (subtract 3). x⁵ ÷ x³ = x². 8 ... WebApr 9, 2024 · The rule for dividing same bases is x^a/x^b=x^ (a-b), so with dividing same bases you subtract the exponents. In the case of the 12s, you subtract -7- (-5), so two negatives in a row create a positive answer which is where the +5 comes from. In the x case, …
WebThe answer is surprisingly simple! A negative number raised to an odd power is always negative, and a negative number raised to an even power is always positive. For example, (-6)^11 is negative and (-6)^12 is positive. (Note well: when writing a negative number to a power, parentheses should be placed around the negative number.
