Answer:

\frac{1}{b^2}

Step-by-step explanation:

Use the laws of exponents to find an equivalent value of b^-2.

The negative law of exponents states that a number with a negative exponents is equal to the reciprocal of that number to the positive exponent.

Basically:

a^-1 = \frac{1}{a^1}

Using this law, you can then simplify b^-2. The reciprocal of b^-2 is 1/b^-2, and by the negative law of exponents, b^-2 changes to a positive exponent:

b^-2 = \frac{1}{b^2}

A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?
motikmotik
X = bat
y = ball

x + y = 1.10

x = y + 1.00

Plug y + 1 in for x

(y+1) + y = 1.1

2y + 1 = 1.1

2y = 0.1

y = 0.05

If the ball is 5 cents, then the bat is 1.1-0.05= $1.05
