How to solve for a and b

murzikaleks [220]

$\bf \begin{cases}
3=a\cdot b^0\\
75=a\cdot b^2
\end{cases}\qquad b^0=1\implies 
\begin{cases}
3=a\cdot 1\implies 3=a\\
----------\\
75=a\cdot b^2\implies 75=3\cdot b^2\\\\
\frac{75}{3}=b^2\implies 25=b^2\\\\
\pm \sqrt{25}=b\implies \pm 5 = b
\end{cases}$

recall, anything raised to the 0, zero, power, is 1, with the sole exception of 0

Check all of the expressions that are equal to the one below.

Vsevolod [243]

Answer:

A. 11•(8 + 7)

B. 8•(11)-7•(11)

C. 11•(7) + 11•(8)

Step-by-step explanation:

The commutative property of multiplication lets you swap the order of the factors in the product:

(8 +7)•11 = 11•(8 +7)

The distributive property lets you eliminate parentheses:

(8 +7)•11 = 8•11 +7•11

And the commutative properties of addition and multiplication let you rearrange this sum of products to ...

(8 +7)•11 = 11•7 +11•8
