Write the expression as a whole number with a negative exponent. Do not evaluate the expression.
WINSTONCH [101]

Answer: \frac{1}{3^6}=3^{-6}

Explanation: Denominators of a fraction can be equivalently written as their value to the power of negative 1. In this case the denominator expression itself  has an exponent of 6, which taken to the power of negative one becomes -6:

\frac{1}{3^6}=(3^6)^{-1}=3^{6(-1)}=3^{-6}

Write 98 as the product of prime factors in ascending order
umka2103 [35]

to write 98 as a product of its prime factors we have to first find the prime factors of 98

prime factors are prime numbers by which the given number can be divided by.

98 we have to keep dividing it by prime numbers

98 is an even number so we can first divide by 2

98 / 2 = 49

49 is a multiple of 7 which too is a prime number so we can divide 49 by 7

49/7 = 7

7 can be divided again by 1

7/7 = 1

98 is divisible by 2 and 7

so 98 written as a product of prime factors is

98 = 2 x 7 x 7
