An expression of 4 as a factor 5 times can be written as (4 \times 4 \times 4 \times 4 \times 4) or simply (4^5). This represents multiplying 4 by itself four additional times, resulting in (1024).
The expression (5 \times 5 \times 5 \times 5) can be written as an exponential expression by using the base (5) and the exponent (4), since there are four factors of (5). Therefore, it can be expressed as (5^4).
To factor the quadratic expression (x^2 + 9x + 20), we need to find two numbers that multiply to 20 (the constant term) and add up to 9 (the coefficient of the linear term). The numbers 4 and 5 satisfy these conditions, as (4 \times 5 = 20) and (4 + 5 = 9). Therefore, we can factor the expression as ((x + 4)(x + 5)).
To factor the quadratic expression (4x^2 - x - 5), we look for two numbers that multiply to (4 \times -5 = -20) and add to (-1) (the coefficient of (x)). The numbers (-5) and (4) work since (-5 + 4 = -1). We can then rewrite the expression as (4x^2 - 5x + 4x - 5) and factor by grouping: (x(4x - 5) + 1(4x - 5)), yielding ((4x - 5)(x + 1)). Thus, the factored form is ((4x - 5)(x + 1)).

The expression (5 \times 5 \times 5 \times 5) can be written as an exponential expression by using the base (5) and the exponent (4), since there are four factors of (5). Therefore, it can be expressed as (5^4).
2(x + 4) or 2(x - 4) depending on the missing operational sign.
no 4 is not a factor of 15 because 4 times 3 is 12 and 4 times 5 is 20
-12
Yes, 5 is a factor of 20 and 5 times 4 = 20
To factor the expression 15a - 25b + 20, we first look for common factors among the terms. The greatest common factor among the coefficients is 5. We can then factor out 5 to get 5(3a - 5b + 4). This is the factored form of the expression 15a - 25b + 20.
To factor the quadratic expression (4x^2 - x - 5), we look for two numbers that multiply to (4 \times -5 = -20) and add to (-1) (the coefficient of (x)). The numbers (-5) and (4) work since (-5 + 4 = -1). We can then rewrite the expression as (4x^2 - 5x + 4x - 5) and factor by grouping: (x(4x - 5) + 1(4x - 5)), yielding ((4x - 5)(x + 1)). Thus, the factored form is ((4x - 5)(x + 1)).
