In the expression 45 the 4 is the base and the 5 is the exponent.
4^5 5 is the exponent.
It is called a denominator.
The expression IS 5*4 - 8.
Expression 1: 2x + 5 - 3y Expression 2: 7(2x + 5 - 3y) Expression 3: 7xy(2 + 5 - 3) Expression 4: 7x(2+5+3y)β
5 x -4
45 - The number at the bottom (4) is the base; the small number at the top (5) is the exponent.
By changing the sign of the second number.
5 + 4 = 9
2
4/5 times 9/2
