You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n
So, here it is:
(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6
The correct answer is the third one - 49 a^2 b^6.
4x+y can’t be factored. There’s no common factor in 4x and y.
Answer:
π =14 cm
Step-by-step explanation:
Given:
circumference of a circle =616 cm
pie(π)=22/7
circumference of a circle=πr^2
616=22/7 *r^2
616*7/22 =r^2
4312/22 =r^2
196=r^2
=r
14 =r
Answer:
thirteen minus four equals eight.
or
Thirteen subtracted by four will equal eight
