What is (-1.2)3 ?
What is -1.728
Write this as a single power, in expanded form, and evaluate.
(22)2
What is (22)(22) = 24 = 16.
Evaluate this expression and state which operation you would do first.
(2 - 3)2 - (4 - 8 + 3)4
What is brackets first and the answer is 0.
What kind of numbers are these?

What is rational numbers.
How are these different? (-4)6 and -46
(-4)6 Means negative 4 to the power of 6 and the answer would be 4096.
-46 Means negative OF 4 to the power of 6 and the answer would be -4096.
Write this as a single power.
(-42)2 x (-42)3 x (-4)4
What is (-414)
Evaluate.
9((0.5)2 + (32 - 8)3)
What is 45/4.
What is 99999999999999990?
-(-(-5)3))
What is -125.
What did Ms. W do wrong here?
(-42)2 x (-42)3 x (-4)4
= (-4)13
What is Ms. W added all the exponents together thinking it was Product Law.
Where did Ms. W go wrong?
(5+2)4 - 3 x 62 + 5
= (7)4 -3 x 36 +5
= 2401 - 3 x 36 +5
= 2398 x 36 + 5
= 86,328 + 5
= 86,333
What is Ms. W added 2401 -3 first before + 5 multiplying -3 x 36. She did not remember BEDMAS.
(2782)5)6)3)4)1)0
What is 1.
Order these powers.
37,-36,(-3)6, 64,-63,(-6)5
What is (-6)5, -36,-63,(-3)6,64,37
What two whole numbers could I substitute for x and y that would make this equation true?
6x = 36y
What is 64 = 362
What values would a and b need to be in order for this to be correct?
(x3y-1)(xayb)= x-4y8
What is a = -7 and b =9 so it looks like this (x3y-1)(x-7y9) = x-4y8
What are the next three numbers in this sequence/
2 ,5 ,10 ,17 ,26
What is 37, 50, 65
