Question

pls answer to this,
$(1 - 0.7) ^{2}$



​

Answer 1

Answer:

0.09

Step-by-step explanation:

We can re-write 1-0.7 as 0.3

Now we have:

(0.3)² = 0.09

Answer 2

$(1-0.7)^{2} =1^2-2.1.(0.7)+(0.7)^2=1-1.4+0.49=0.09$

$(1-0.7)^{2} =(0.3)^2=0.09$

P/s: $(A-B)^2=A^2-2AB+B^2$

Ok done. Thank to me :>
