Apply the Zero Power Rule to create an equivalent expression to 9⋅(−33)0+32(8−270).(2 points)
9⋅(−33)0+32(8−270) =
⋅
+32(
–
)
Applying the Zero Power Rule, any number raised to the power of zero is equal to 1. Therefore, the equivalent expression to 9⋅(−33)^0+32(8−270) is:
9⋅1 + 32(8−270).
Solve the expression 15⋅805+4(70−6).(1 point)
15⋅805+4(70−6)=
To solve the expression 15⋅805+4(70−6), we need to first evaluate the expression within parentheses:
70 - 6 = 64
Next, we can substitute this result back into the original expression:
15⋅805 + 4(64)
Now, we can perform the multiplication:
15⋅805 = 12,075
4(64) = 256
And finally, we can add the two results together:
12,075 + 256 = 12,331
Therefore, the solution is 12,331.
Use the Power Rule of Exponents to simplify (10^3)^6
To simplify (10^3)^6 using the Power Rule of Exponents, we multiply the exponents:
(10^3)^6 = 10^(3*6)
3*6 = 18
Therefore, (10^3)^6 simplifies to 10^18.
