Question

simplify (12 power 0 + 25*1/2)(20 power 0 * 1 power -20

Answer 1

Answer:

Simplification results in the value of 6.

Step-by-step explanation:

Given:

$= ({12}^{0} + {25}^{ \frac{1}{2} } )( {20}^{0} \times {1}^{ - 20} ) \\ since \: {a}^{0} = 1 \\ = (1 + \sqrt{25} )(1 \times {1}^{ - 20} ) \\ since \: {a}^{ - x} = \frac{1}{ {a}^{x} } \: and \: \sqrt{25} = 5 \\ = (1 + 5)( \frac{1}{ {1}^{20} } ) \\ since \: {1}^{x} = 1 \: and \: \frac{x}{1} = x \\ = (6)(1) \\ \\ = 6$
