Question

Please ans thous Math question..
1. 0.006+ 0. 92 +0. i34=?

2.If x + y = 7 & x – y = V5 then xy(x2 + y2) =??

​

Answer 1

Step-by-step explanation:

${ \huge \fbox \pink {A}\fbox \blue {n} \fbox \purple {s} \fbox \green{w} \fbox \red {e} \fbox \orange {r}}$

${ \huge {\underline {\underline {\mathtt {\blue{1)}}}}}}$

0.006+ 0. 92 +0. 834 = 1.76

${ \huge {\underline {\underline {\mathtt {\blue{2)}}}}}}$

$\huge{ \mathtt {GIVEN}}$

x + y = 7

xy = 2

${ \mathtt{To \: Find}} \: { \bold{x²-y²}}$

${ \mathtt{ \underline{Solution}}}$

x + y= 7 ( On squaring both sides)

=> (x + y)² = 7²

=> (x + y)² = 7²=> x² + y² +2xy = 49

=> (x + y)² = 7²=> x² + y² +2xy = 49=> x² + y² + 4 = 49

${ { \boxed {\mathtt{x² + y² = 45}}}}$

${ \huge{ {\boxed{ \tt{To \: find \: x-y}}}}}$

(x - y)²= x²+y²-2xy

=> x-y² = 45-4

=> x-y² = √41

ANSWER- 7 root 41
