If p×qsquared t when q=3,t=5,and p=90,find a when p =4and t= 8

To find the value of a, we can substitute the given values of p, q, and t into the equation:

p × q^2 × t = a

Given p = 90, q = 3, and t = 5:

90 × 3^2 × 5 = a
90 × 9 × 5 = a
810 × 5 = a
4050 = a

Therefore, when p = 4 and t = 8, the value of a is 4050.
