Question

7.1^(6)*7.1^(7) single exponential expression

Answer 1

7.1^13

Explanation:

The base is 7.1, the exponents are 6 and then 7. The rule is that if you have the same base and you are multiplying, you can add the exponents. Its an exponent rule, but think of it as a short cut. Worth remembering!

Use the meaning of exponents to help remember/understand the shortcut.

7.1^6 means

7.1×7.1×7.1×7.1×7.1×7.1

and

7.1^7 means

7.1×7.1×7.1×7.1×7.1×7.1×7.1

if you times both of those together, you'll have thirteen 7.1 being multiplied together! That's 7.1^13

but who wants to write all that out?!? Literally nobody. Think of a rule as a shortcut! Good luck!
