Answer:
An exponent can be any small number, which is almost always in the top write corner of a whole number.
Step-by-step explanation:
For example, 4(6). the 6 would be in the top right corner. This is an easier way of writing 4x4x4x4x4x4.
Answer:
0
Step-by-step explanation:
To factorise it start with putting the xs in brackets.
(x )(x )
Then you must find 2 numbers which multiply to +81 and sum to -18.
81 is the product of 9×9 or -9×-9.
9+9=+18
-9+-9=-18
So they two numbers must be -9.
So factorised it is (x-9)(x-9) or (x-9)^2
2 = X = -1
2
2. 2(4x+2) - (x-4) = 3(x+2)
Expand tge expression
= 8x + 4 -x +4 = 3x + 6
CLT ( Combine like terms)
= 7x + 8 = 3x + 6
Rearrange the terms
7x - 3x = 6 - 8
CLT
4x = -2
Divide both sides by 4
x = -2
4
x = -1
2
