Length = x + y

Area of a square = Length x Length

The expression can be :

1) Area of the square = (x + y)(x + y)

2) Area of the square = (x + y)²

3) Area of the square = x² + 2xy + y²

What values of a and b make the equation true? StartRoot 648 EndRoot = StartRoot 2 Superscript a Baseline times 3 Superscript b

kramer

Option C: $a=3, b=4$ is the value of a and b

Explanation:

Given that the expression $\sqrt{648}=\sqrt{2^a\times3^b}$

We need to determine the value of a and b

Let us consider the term $\sqrt{648}$ and take the prime factorization of the term 648

Thus, we have,

648 divides by 2,

$648=2 \cdot 324$

324 divides by 2,

$648=2 \cdot 2 \cdot 162$

162 divides by 2,

$648=2 \cdot 2 \cdot 2 \cdot 81$

81 divides by 3,

$648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 27$

27 divides by 3,

$648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 9$

9 divides by 3,

$648=2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 3 \cdot 3$

Thus, we have,

$\sqrt{648}=\sqrt{2^{3} \cdot 3^{4}}$

Therefore, equating the powers of 2 and 3, we get,

$a=3, b=4$

Hence, the value of a and b is 3 and 4

Thus, Option C is the correct answer.

Someone plz answer i rlly need help Solve for a.<br><br> a+(−1.6)=−3.7

Norma-Jean [14]

Hi there!

All you need to do to solve for a is add 1.6 to both sides of the equation.

It will look like this:
a - 1.6 + 1.6 = -3.7 + 1.6

After this you will see that a = -2.1.

Hope this helps!
When in doubt just replace a with -2.1 and see if you still get -3.7. :)
