Q. Write the following expression without negative exponents and without parentheses.(10x)−2Answer:
Use Rule for Negative Exponents: To remove the negative exponent, we can use the rule that a−n=an1, where a is the base and n is the exponent. This means we need to take the reciprocal of the base when the exponent is negative.
Apply Rule to (10x)−2: Applying this rule to (10x)−2, we get (10x)21. This removes the negative exponent.
Square the Base: Now we need to square the base, which means we will square both 10 and x. So (10x)2 becomes 102×x2.
Calculate Final Expression: Calculating 102 gives us 100. So we have 1/(100x2), which is the expression without negative exponents and without parentheses.
