Step-by-step explanation:
a · b = (4)(3) + (5)(6)
a · b = 12 + 30
a · b = 42
Answer: The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

X = 3
You're welcome.
Step-by-step explanation:
Hi there!
The rearranged equation solving for y is “y = 4a”
Move all the terms not containing the y to the right side of the equation.
4y = 16a
Then divide both sides by 4!
Hope this helps!
Answer:
b > 17
Step-by-step explanation:
In this question, you would have to solve the inequality.
Solve for b:
17b - 21 > 12b + 64
Subtract 12b from both sides:
5b - 21 > 64
Add 21 to both sides
5b > 85
Divide both sides by 5:
b > 17
b > 17 will be your answer.
