360 because you multiply 8 x 5 x 9
Answer:
7
Step-by-step explanation:
let the no. be 'x'
By question,
2x-8=6
or, 2x =6+8
or,2x = 14
or,x = 7
therefore, the no. is 7.
12,000, because 11,900>11,500, so you round it up to 12,000
1/5 = 2/10
1/2 = 5/10
1/10 + 2/10 + 5/10 = 8/10.
8/10 = 4/5.
4/5 is your final answer.
When we have a negative exponent, we use the negative exponent property: a negative exponent with it’s base must be the reciprocal of the base and negative exponent, in order to make it a positive exponent.
Solving:
(-3)^-3/1
We made the base of -3 and exponent of -3 a fraction over 1, because we will need to take the reciprocal (flipped upside down fraction) of it.
1/(-3)^3
We now have a positive exponent. We took the reciprocal of (-3)^-3/1, so we just flipped the fraction upside down to 1/(-3)^3, which gave us a positive exponent.
1/(-3)^3 = 1/(-3)(-3)(-3) by the definition of an exponent (how many times a number multiplies itself).
Now , we just simply by multiplying -3 to itself 3 times.
1/-27 is the answer.
