Rewrite the exponential expression 25^3/2as a radical expression-<br> plss helpp
Agata [3.3K]

Answer:

\huge\boxed{\sqrt{25^{3}}}

Step-by-step explanation:

When we have a number to a fraction power, we need to note that

  • It's the same as taking the denominator root of the base to the numerator power

Basically, for example, 5^{\frac{1}{2}} is the same as \sqrt{5} since the numerator is 1 (5^1 = 5) and the denominator is 2 (\sqrt{5}).

Applying this same logic to 25^{\frac{3}{2}} -

25^{3}

\sqrt{25^3}

Hope this helped!

HELP WITH MY MATH EXAM i don't know what to do and my head hurts a lot
gogolik [260]

Answer:

x = 154/13

Step-by-step explanation:

You are given the measures of all three angles in a triangle

so according to the Triangle Sum Theorem:

∠MNO + ∠OMN + ∠NOP = 180

1. Substitute the measures of the angles into the equation:

(3x + 11) + (2x + 20) + (8x - 5) = 180

2. Combine like terms:

(3x + 2x + 8x) + (11 + 20 -5) = 180

13x + 26 = 180

3. Isolate x by subtratcing 26 from both sides

13x + 26 -26 = 180 -26

13x  = 154

4. Solve for x by dividing both sides by 13

13x/13 = 154/13

x = 154/13
