The answer is 8 and heres why:

$64^{\frac{3}{6}} \\\frac{3}{6}=\frac{1}{2} \\ \\64^{\frac{1}{2}} \\ \\\mathrm{Factor\:the\:number:\:}\:64=8^2 \\\left(8^2\right)^{\frac{1}{2}} \\ \\\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc} \\\left(8^2\right)^{\frac{1}{2}}=8^{2\cdot \frac{1}{2}}=8$

And that is how you solve this promblem :-)

0.27 (repeating) into a fraction. Simplify if needed.

WARRIOR [948]

Dont ask me why...I cant really explain it...but if u have 1 repeating decimal, u put it over 9. If u have 2 repeating decimals, u put it over 99....3 repeating decimals, put it over 999.

Examples :
0.7 (repeating) = 7/9
0.27 (repeating) = 27/99 when simplified = 3/11 <===
0.444 (repeating = 444/999

The depth of a lake in cedar burg changes over time due to rain fall and evaporation this year it was 39 feet which is 25% less

Nostrana [21]

Answer:

The depth of the lake last year was 52 feet

Step-by-step explanation:

Given as :

This year depth of lake = 39 feet

Let the last year depth of lake = x feet

Now,

According to question :

The depth this year is 25% less than that of last year

I.e 39 feet = x - 25% of x

Or, 39 feet = $\frac{75x}{100}$

or, x = $\frac{3900}{75}$

∴ x = 52 feet

Hence The depth of the lake last year was 52 feet Answer
