Answer:

We just have to solve each power.

8^{2} = 8 \times 8 = 64\\10^{-2} =\frac{1}{10^{2} } =\frac{1}{100}=0.01 \\(-4)^{4}=(-4) \times (-4) \times (-4) \times (-4)=256 \\(-6)^{4}=(-6) \times (-6) \times (-6) \times (-6)=1,296

Remember, to solve a power, we just need to multiply its base as many times indicates its exponent.

It's important to know that the negative exponent indicates a position, that's why in the second exercise we needed to change the position of the power to continue.

Answer:

y = 0.3

Step-by-step explanation:

Solve for y:

\longrightarrow (3.2y - 1.8) - (5.2 y + 3.4) = -5.8

-(5.2y + 3.4) = -5.2y - 3.4:

\longrightarrow3.2y - 1.8 -5.2y - 3.4 = -5.8

Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):

\longrightarrow (3.2y - 5.2y) + (-1.8 - 3.4) = -5.8

3.2y - 5.2y = -2 y:

\longrightarrow -2y + (-1.8 - 3.4) = -5.8

-1.8 - 3.4 = -5.2:

\longrightarrow -5.2 - 2y = -5.8

Add 5.2` to both sides:

\longrightarrow (5.2 - 5.2) - 2y = 5.2 - 5.8

5.2 - 5.2 = 0:

\longrightarrow -2y = 5.2 - 5.8

5.2 - 5.8 = -0.6:

\longrightarrow -2y = -0.6

Divide both sides of -2y = -0.6 by -2:

\longrightarrow \sf \dfrac{-2}{-2}y = \dfrac{-0.6}{-2}

\sf \dfrac{-2}{-2} = 1:

\longrightarrow \sf y = \dfrac{-0.6}{-2}

\sf \dfrac{-0.6}{-2} = 0.3:

\longrightarrow y = 0.3
