When multiplying exponents, remember the first rule: when multiplying similar bases, add powers together. 52% + 56% =? The bases of the equation remain unchanged, while the exponents' values are added together. Adding the exponents is only a quick way to get at the answer. Simply add the exponents to multiply exponential expressions with the same base. Simplify. The product rule applies because the base of both exponents is a. With a common basis, add the exponents.

Answer:
41 minutes
Step-by-step explanation:
We are given;
Time spent on homework = 90 minutes
Time spent reading = 2/3 hours = 2/3 × 60 minutes = 40 minutes
Time spent making lunch = 540 seconds = 540/60 minutes = 9 minutes
We want to find how many more minutes Roberto spent doing homework than he did reading and making his lunch.
Thus;
Time spent on reading and making lunch = 40 + 9 = 49 minutes
Hence, the word "how many more" means we will subtract 49 from 90.
So, "how many more minutes" = 90 - 49 = 41 minutes

Answer:
The perfect square of 3*4 is 9*16
Step-by-step explanation:
A perfect square is a number that can be expressed as the product of two equal integers.
For example 64 is a perfect square because if we multiply 8 two times we will get 64.
Thus the given expression is 3 * 4.
To find perfect square we square the numbers:
3² = 3*3 = 9
4² = 4*4 = 16
Thus the perfect square of 3*4 is 9*16 ....
