Question

(х+у)х4+9у при х=70 у=100

Answer 1

(х+у)*4+9у=4х+4у+9у=4х+13у
если х=70;у=100, то 4*70+13*100=280+1300=1580

Answer 2

(70+100)*4+9*100=170*4+900=1580

Answer 3

To evaluate the expression (х+у)х4+9у at х=70 and у=100, we substitute the values of х and у into the expression:

(70 + 100) × 70^4 + 9 × 100 = 170 × 240100000 + 900 = 40,818,017,000

Therefore, when х=70 and у=100, the value of the expression (х+у)х4+9у is 40,818,017,000.
