An exponent, such as the 4 in the expression 94, means: the number of times the number before the exponent is multiplied by itself (9 x 9 x 9x 9). O the number of times the number before the exponent is multiplied by 10 (9 x 10 x 10x 10 x 10). O the number to multiply the first number by (9 x 4). O the number of times the digit is written (9999). the number lo add to the first number (9 +4).
