The value of d is 4 by law of exponents.
What are exponents?
The mathematical procedure known as exponentiation uses the base b and the exponent, or power, n. Its translation is "b to the n" and its symbol is Bn. The how many times a number has been amplified by itself is known as an exponent. When written as 23, the phrase "2 to the third" actually means "2 x 2 x 2 = 8," not 23, and "2 x 3 = 6," respectively.
Keep in mind that a number multiplied by one equals the original number.
Exponents are a way to express very big numbers as powers of smaller numbers. The exponent, so to speak, is the amount of times an integer has been multiplied by itself.
Applying the laws of exponents,
Given that, -3 = -19 +d/5
-3 = -19 +d5
-3 + 19=d5
d = 4
