Answer:
(5 square root 2-4 square root 3) (5 square root 2-4 square root 3)
= 98 - 40[tex]\sqrt{6}[/tex]
Step-by-step explanation:
i) (5[tex]\sqrt{2}[/tex] - 4[tex]\sqrt{3}[/tex]) × (5√2 - 4√3)
=(5[tex]\sqrt{2}[/tex] × 5[tex]\sqrt{2}[/tex]) - (5[tex]\sqrt{2}[/tex] × 4[tex]\sqrt{3}[/tex]) - (4[tex]\sqrt{3}[/tex] × 5[tex]\sqrt{2}[/tex]) + (4[tex]\sqrt{3}[/tex] × 4[tex]\sqrt{3}[/tex])
= 50 - 20[tex]\sqrt{6}[/tex] - 20[tex]\sqrt{6}[/tex] + 48
= 98 - 40[tex]\sqrt{6}[/tex]
Answer:
98 - 40√6
Step-by-step explanation:
The words expression can be represented as follows:
(5√2 - 4√3) (5√2 - 4√3)
The question is to find the products .
(5√2 - 4√3) (5√2 - 4√3)
Multiply through to open the bracket
25 × 2 - 20√6- 20√6 + 16 × 3
50 - 20√6 - 20√6 + 48
50 - 40√6 + 48
50 + 48 - 40√6
98 - 40√6
