Question

Please help with 24-26

Answer 1

20. - 23. are all correct.

24. A number raised to the zero power equals 1. 0 to the 0 power may be undefined according to some, but any number other than zero raised to the zero power is 1. We assume x is not equal to zero.

$-2x^0 = -2 \times 1 = -2$

25. To raise a product to a power, raise each factor to the power. Assume that none of the variables equal zero.

$(11abx)^0 = 11^0 \times a^0b^0x^0 = 1 \times 1 \times 1 \times 1 = 1$

26. Assume all variables are non-zero.

$(xy)^0 - (pq)^0 = 1 - 1 = 0$

Answer 2

24

The power 0 only affects the x. x^0 = 1

-2 * 1 = -2

25

Here everything inside the brackets is affected by the 0.

(11abx)^0 = 1 There is nothing left over.

26

(xy)^0 = 1

(pq)^0 = 1

1 - 1 = 0
