How do I do this problem?
Elenna [48]
Roots can be written as fraction exponents. An exponent of 1/2 means the square root.

(12 x^{4})^{1/2} =  \sqrt{12 x^{4} }  \\  \\ \sqrt{12 x^{4} } =  \sqrt{3*4*x^{2}*x^{2}} = 2x^{2} \sqrt{3}

Max earned a 85% on his test. if there were 40 questions on the test how many did he get correct?
wel
Max would have had to have gotten 34 out of 40 questions correct. Here's why:

\frac{x}{40} =  \frac{85}{100} 

(40)(85) = (x)(100)



3400 = 100x

 \frac{3400}{100} = x


34 =x

GUYS QUICK! what is the surface area of a sphere that has a radius of 5 cm
alisha [4.7K]

Answer:

100 pi cm^2

or approximately 314 cm^2

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

The radius is 5

SA = 4 *pi * 5^2

SA = 4*pi(25

SA = 100 pi cm^2

If pi is 3.14

SA = 100 *3.14 = 314 cm^2
