What values of a and b make the equation true? sqrt(648)=sqrt(2^a•3^b)

Anuta_ua [19.1K]

ANSWER

The value of a and b are:

$a=3,b=4$

EXPLANATION

The expression given to us is

$\sqrt{648} = \sqrt{ {2}^{a} \times {3}^{b} }$

We square both sides of the equation to obtain

$648= {2}^{a} \times {3}^{b}$

We now find the prime factorization of 648 to obtain,

${2}^{3} \times {3}^{4} = {2}^{a} \times {3}^{b}$

We now compare the exponents on both sides of the equation to obtain,

$a=3,b=4$

Therefore the correct option is C

Steven combines 7.49 liters of red paint with 6.26 liters of blue paint to make purple paint. He pours the paint equally into 4

kondaur [170]

Answer:

3.3075 liters of paint

Step-by-step explanation:

7.40 (red paint) + 6.26 (blue paint ) = 13.66 (purple paint)

He pours 13.66 liters of purple paint equally into 4 containers and has 0.43 liters left.

x + x + x + x = 13.66 - 0.43

4x = 13.23

x = 13.23/4

x = 3.3075
