## anonymous one year ago can someone help me plz What is the value of 19 + 5a^4 – 3b^2 when a = 2 and b = −4?

1. campbell_st

just make the correct substitution and calculate it becomes $19 + 5 \times 2^4 - 3 \times (-4)^2$ enter it into a calculator the way its written about and you'll get the correct answer
