How to do a exponent with the negative base?
2 answers:
Examples :
(-2)^3 = (-2)(-2)(-2) = - 8
(-3)^4 = (-3)(-3)(-3)(-3) = 81
(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1
** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative
** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25
Any number raised to a negative exponent could be written as follows:
a⁻ⁿ = 1/aⁿ
a⁻² = 1/a²
a⁻²³ = 1/a²³
a⁻ˣ = 1/aˣ

Step-by-step explanation:
If your asking for the area you multiply 40 times 25
It will be 21/40
probability getting both white marbles
3/8×4/10=12/80
probability getting both black marbles
5/8×6/10=30/80
12/80+30/80=42/80= 21/80
