Question

sa se afle a+b unde a= 4√2•(-3√2)+25 si b= 8√27:(2√3)-13​

Answer 1

Răspuns:

a+b=1+(-1)==> a+b=0

Explicație pas cu pas:

a=4√2•(-3√2)+25

a= -12•2+25

a= -24+25

a=1

b=8√27:(2√3)-13

b=8•3√3:(2√3)-13

b=24√3:(2√3)-13

b=12-13

b= -1

Answer 2

1. Răspuns:

• a=4✓2•(-3✓2)+25=-4✓2•3✓2+25=-4•2•3+25=-24+25=1
• b=8✓27:(2✓3)-13=4✓9-13=4•3-13=12-13=-1

a+b=1+(-1)=0
